SurveyJS
Open-Source JSON Form Builder to Create Dynamic Forms Right in Your App. With SurveyJS form UI libraries, you can build and style forms in a fully-integrated drag & drop form builder, render them in your JS app, and store form submission data in any backend, inc. PHP, ASP.NET Core, and Node.js.
I find that Notesnook has potential as a clone of Evernote. It claims to be a more privacy focussed and secure then Evernote. But it is just as expensive with a lot less features and the free plan is like a barebones demo (max 5 tags, 3 notebooks and no rich text editing). Though it does have a roadmap and active discord.
Obsidian is a markdown, local storage and very fast note taking app. Though it lacks rich text editing and requires markdown knowledge and even more scripting/coding knowledge if you want to take full advantage. After trying Obsidian for 6 month it made me appreciate the simplicity of Evernote a lot more!
